I think the general consensus is to keep the `java.base` module minimal. IIRC, the reason we have `PCK` charsets in Un*x platforms was that it was required to boot Solaris in Japanese env (sorry if I am wrong). So I would remove it from `java.base` if possible. Thus moving those IBM* encodings that are equivalent to SJIS into `java.base` is something I would not want to do. It is definitely not a compatibility issue. ------------- PR: https://git.openjdk.org/jdk/pull/11908
